Jeff 330CI 02-23-2009 19:00:33 216.46.159.73 21396 Report to Moderator	Today I was using my 1965 Nuffield 10/60 Tractor. After about 30 minutes of light use, the engine block was so hot that it could boil water. It was cold out today and I was not working it hard. It has never got that hot before even after hours of hard useage on a hot day. The oil dipstick was even hot enough to boil water. The coolant was full and was operating at the normal operating temperature. This has never happened before. Any ideas? Thanks, Jeff This post was edited by Jeff 330CI at 19:02:42 02/23/09.

If the engine is that hot, and the coolant temp is still showing normal, it may be that your gauge and/or it"s bordon tube have also taken this opportunity to quit. After we bought one of our 10/60, the tractor would boil just by driving it down a road, the water pump showed no signs of problems, no leaks or anything like that, but when we pulled it apart the keyway and woodruff key that drive the impeller were so worn that the impeller would not turn under load. It"s not the first one I"ve done on 10/60 either... mind they are at least 40 years old now. Hope that helps, Oli.   [Reply]   [Send Email]
